WELDED WROUGHT-IRON ANNEALING-POT.

Specification of Letters Patent.

' Patented May 19, 1914:.

Application filed May 26, 1909. Serial No. 498,542.

To all whom it may concern Be it known that I, EMIL THEoDon LAM- MINE, asubject of the German Emperor,and resident of Cologne, Germany, formerlyresiding in Miilheim on the Rhine, Germany, have invented an ImprovedWelded VVrought-Iron Annealing-Pot, of which the following is aspecification,

The object of the invention shows a special form of construction of thewrought iron annealing cylinder according to patent application SerialNo. 431272 of May 6th, 1909.

The present'inventiondiffers from the ob ject of that application inthat the upper molded rim, separately made, of profile iron is combinedwith the carrying lugs and the casing by means of welding. The advantageof this change consists therein that a much greater stability of theannealing cylinder together with abetter and tighter fit:

ting of the lid is attained, a deformation of the cylinder at the upperend,'which is to be observed in larger pots on account of the highclaims made thereon, is precluded during the heating; Additiona ly thisseparately constructed and welded on rim makes another use of the samepossible in case the casing should have become useless, It is the samewhether the annealing cylinder has smooth or profiled walls foradjusting the rim; the profile iron may be so worked as to serve asasupport for two lids.

The drawing represents a central sectional view of an annealing potformed -in accordance'with my invention. v

Referring to the drawing specifically, the upper part of the cylinder 11s surmounted by a rim constructed of profile iron 2 and again on thissit the carrying lugs 3. All the junctions are performed by means ofwelding. I

The term profile iron as used herein is intended to cover a metalstructure ofa desired crosssection suitable for the, purposes of theinvention.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. As an article of manufacture, an annealing cylinderconsisting of a body, and a cover receiving rim for said cylinderannular-1y channeled to form a cover seat, the lower portion of'said rimbeing formed as a continuation of the wall of said cylinder and invertical alincinent therewith and having its lower edge welded to theupper edge of said cylinder some distance below the said seat.

2. As an article of manufacture, an annealing cylinder consisting of abody having a wrought iron wall, the upper edge of which is channeled,and a cover receiving rim for said cylinder, the lower portion of saidrim being formed with a .cover seat and a lower portion constituting acontinuation of the wall of said cylinder and in vertical alinementtherewith, and having its lower edge rounded and welded to the channeledupper edge of said cylinder at a point some distance below the coverseat, said lower portion being of greater thickness than the wall of thecylinder, and having, its upper portion also thickened and bent to forma sl1oulder to receive a cover.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

EMIL THEODOR LAMMINE.
